What is a prior authorization?

Prior authorization is your health plan asking to decide before, not after. HealthCare.gov's definition: approval from a health plan that may be required before you get a service or fill a prescription for it to be covered. The plan wants to check that the treatment meets its rules - medical necessity, cheaper alternatives tried first, the drug on its formulary - before it commits to paying. The expensive, brand-new, or easily overused treatments attract it most: brand-name drugs with generic cousins, MRIs, surgeries, specialty medicines. The mechanics matter because they catch people out. Your doctor's office submits the prior authorization - you cannot file it yourself - and the pharmacy or hospital usually triggers it by telling you the claim was rejected for needing one. Then you wait, which is why the first question to ask when any new prescription arrives is: does this need prior authorization? Your doctor can often pick a covered alternative instead, skipping the queue entirely. The federal direction is friendlier than the reputation: CMS's 2024 final rule now requires the big regulated payers to answer prior authorization requests within 72 hours for urgent cases and 7 calendar days for standard ones, and from 2026 to give a specific reason when they deny. If it is denied, that denial is appealable - your doctor can argue medical necessity, and many denials flip.
